4 1 General information about ETS 1.1 General aspects KNX is a fully integrated system for home and building automation for the implementation of upward compatible, flexible and cost-effective solutions. Its functional versatility cannot only be used in simple and limited installations but also enables solutions for the entire building sector. KNX thus corresponds to the requirements of the electrical trade including project design and installation, commissioning, operation of the bus system and maintenance. The planning, project design and commissioning of a KNX installation requires a software tool for building designers and electrical installers that is clearly structured and simple to use. An extensive online Help file is available to the user. The user can at any time access help for the currently opened window via the F1 button. The project design of a building, in which KNX should be used, initially does not differ from conventional electrical planning. The following aspects must be clarified by the planner in the preliminary stages: the type and use of the building, the building system components that are to be implemented and their functions, type and frequency of changes of use, special requirements of the clients, budget The planning of the electrical installation is carried out as for a conventional installation according to the generally recognised rules of technology, the connection conditions of the utility as well as the usual planning guidelines, implementary regulations and dimensioning provisions. 1.2 The ETS concept For the planning, project design and commissioning of KNX systems, a uniform program for the project design and commissioning of the KNX system is available for planners and installers. ETS stands for Engineering Tool Software. ETS is a registered trademark of the. ETS4 is the current version of ETS. On the one hand, ETS4 is a newly developed software program: during its development particular emphasis was placed on keeping the user interface very similar to that of the previous versions. On the other hand, the display and operating philosophy of the user interface of ETS4 has been completely reworked. Display and operation has been adapted to current standards. In this way, operation and orientation has been clearly simplified in comparison to ETS3. KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 4/41

5 1.3 System requirements The following operating systems (as 32/64 bit) are supported in principle: MS Windows XP MS Windows Vista MS Windows 7 MS Windows 8 MS Windows Server 2003/2008 Details about this and the required hardware can be found on the KNX home page on Installation of ETS You can only obtain ETS from via internet in the KNX online shop (address If you have downloaded the software from the internet and have unzipped the downloaded file, you start the installation by executing the installation program ETS4Setup.exe. KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 5/41

6 Figure 1: Licensing 1.5 Licences There are four versions available, all as a PC-dependent key or a non PC-dependant dongle (except for the demo): Demo: Full functionality, max. 3 devices per project, this version is free of charge. Lite: Full functionality, max. 20 devices per project. Professional: Full functionality, no restrictions as regards number of devices which can be installed and the number of projects which can be created There is also the Supplementary version. This version is intended as an additional licence for the full Professional version on a second PC (commissioning PC/Notebook). In all cases, the ETS program is installed in full. The mode, in which ETS subsequently runs, depends on the type of licence key. After installation, the program first runs as a demo version. You can start the process for purchasing and installing licences, by clicking the Licensing button in the Version Information box in the ETS dash board, which is opened after starting ETS. Pressing the Request Licence button leads directly to the KNX online shop. This requires an active online connection. On the pages of the online shop, you will also find detailed information about the licensing process. KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 6/41

7 The following key types exist: PC dependent key: this key activates the license only on the PC on which the ETS license has been installed. PC independent key: this key does not refer to the PC hardware, but refers to a dongle which also has to be ordered from. This dongle must be inserted in the USB port of the computer. This type of key is a little bit more expensive ETS also allows distant configuration or maintenance of installations (via Internet, called iets) Since the introduction of ETS 4.1 it is possible to extend the functionality of ETS via programs called Apps. These Apps are also available in the KNX Online Shop and they are licensed in the same way as described before. Some Apps are developed by KNX Association, others by KNX manufacturers. Examples of such Apps are: online product catalog, graphical configuration of ETS projects, Project compare, Replace product. For some of these apps a fee needs to be paid. In order to prepare yourself for a future KNX basic course and to get acquainted with ETS, you can sign up for the ETS ecampus. This is free of charge and you only need to register yourself in the Online Shop. KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 7/41

8 1.6 Project design with ETS The principles The following steps represent the chronological order for project design with ETS. Carry out the ETS settings Read in or convert product databases Create the project with the necessary data Set up the structure of the project (building structure/bus topology) Insert KNX products (devices with corresponding application) into the building structure Set the parameters of the KNX products according to requirements Create group addresses Link the communication objects of the KNX products with the group addresses Assign the configured KNX products to the bus topology (final definition of the physical address) Assign the configured KNX products to the installed functions (optional) Check the project design Print out the documentation Save the project It is possible to deviate from this sequence in individual cases. Some steps can be omitted for smaller projects. Additional steps are necessary in large projects (team projects). KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 8/41

9 1.7 Starting ETS After the installation, ETS can be started by clicking the icon on the desktop or via the newly created program group called KNX. When you open up ETS, a window appears which is referred to as the dashboard. Figure 2: Dashboard It contains the following elements: A Quick Actions bar (1) for frequently required functions. A menu bar (2). If you click on elements of the menu bar, you directly access the project design view of ETS. A tab (3) via which you select what is currently displayed in the workspace (4). You can access the dashboard again at any time by clicking on the small green ETS field in the top left-hand corner of the ETS window. KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 9/41

10 1.8 Dashboard tabs Overview tab When ETS is opened, the Overview tab is selected so that the fields displayed in figure 3 are visible in the workspace: Figure 3: Dashboard, Overview tab selected By double clicking on a project in window area A, you select the project that is to be edited. Via area B, you access the licensing feature. If you have an existing connection to the internet, current news about the is shown in areas C and D. KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 10/41

11 1.8.2 Projects tab Figure 4: Dashboard, Projects tab selected You can create a new project here, select a project for editing and set the properties of the projects. Further information can be found below in section 2: Opening a project with ETS. Projects can likewise be imported and exported via this window. Further information about the import and export is described below in a separate section Catalogs tab The product data of the manufacturers is managed under Catalogs. After the installation, the ETS database is empty. To be able to work with ETS, product data from the manufacturers must be imported into this database. The import function of ETS is used for this purpose. Details about the import and export are described below in a separate section. The manufacturers product databases can be obtained free of charge on a CD or via the internet. The window that is shown after selecting the Catalogs tab is displayed again during the project design stage when selecting devices. This window is therefore described in more detail further down in this section (see: Catalogs) KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 11/41

12 1.8.4 Database tab Figure 5: Dashboard, Database tab selected In the Database window, you can select the currently edited database, generate a new database or create a backup of the database. Select database: If you are working with several databases, you can select here the database you wish to use. You can specify under Settings (see next tab) in which directory the databases are located. KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 12/41

13 Figure 6: Select database You can likewise generate a new database via the New button. The result is however an empty database, into which you need to import the product data of the manufacturers. Backup now or Restore backup. You require this function on the one hand to create a backup copy of your database and on the other hand to port a database to another computer. The file that was created during the backup process must be inserted via the option Restore backup on the other computer. Only then does ETS work with this database. A database that has simply been copied cannot be handled by ETS (protective function of the MS database system). An automatic backup function can also be set under the Settings tab. Further details about this can be found in the explanatory notes on the settings. Central database repository Figure 7: Central database repository KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 13/41

14 A further function under the Database tab makes it possible to store the database not on the local computer but e.g. on a network drive. This is especially useful, when working with several users in one database. However, only one user can work with the database at one time. If required, you must select the option Use central database repository and when you wish to work with this database, you must check out this database to avoid that some else simultaneously carries out changes to the database content. Once you have finished editing the database, you must check this database back into the central database repository again. A prerequisite for this procedure is that the database in question has only been added once to the central database repository. The path of the central database repository can also be entered in this window Settings tab Figure 8: Dashboard, Settings tab selected The settings are divided over eight different areas, which one can select by clicking on the terms in the left half of the window: Presentation General. Here you can influence the properties and appearance of ETS in some cases. For details, please refer to the online Help feature in ETS. Presentation Language. Here you can select the language of ETS. Communication. Here you can set the interface that is used for bus access. For details about this topic, please refer to the commissioning chapter of this training documentation. KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 14/41

15 Database Figure 9: Dashboard, Settings tab, Database submenu In addition to selecting the path where the ETS databases should be stored, you can select here, whether you wish to create a backup each time you close ETS. If you have ticked the option Append date and time on backup file name, the current date and time is attached to the file name for each backup file. Software Updates. When enabled, ETS checks automatically via the internet whether there are new updates of ETS available. If this is the case, ETS signals this and the new update is installed if requested. Troubleshooting. Here you define the logging level for documenting your work in ETS log files for potential troubleshooting by the. Import. Setting the behaviour of the Import Wizard and the installation of plug-ins. For further details, see below under the description of the import functions. Shortcuts. Here all shortcuts are displayed, which can be adapted according to your habits. Shortcuts enable the experienced user to work quicker with ETS. 1.9 The import functions The import function enables both the import of product data as well as projects. You can retrieve this function from different places in ETS. This can be done via the Quick Actions bar on the dashboard and in the Projects and Catalogs tabs via the Import... button. You can also retrieve the import function at any time when working in the project design view of ETS by selecting the Import button in the Catalogs window. KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 15/41

16 Figure 10: Import Wizard When importing data, one can be guided by the Import Wizard, which is particularly advisable in the beginning. To do so, this function must be enabled in the ETS settings (see section 1.8.5) Product data import You can obtain product data from the manufacturers either on a CD or via the internet. It is also possible to import product data from existing ETS3 databases. Databases from which you can import data can be recognised by their file extensions: Files with the extension.knxprod are databases in XML data format for ETS4. Product databases for ETS3 and ETS2 have the file extension.vd?. The question mark stands for the numbers 1 5 or an x, depending on which ETS version the data was originally intended for. Databases with the ending.db are databases from ETS3 or ETS2. You select a file by pressing the button in the Import Wizard on page 1 File. You will then see the selection box displayed in the screenshot. This window is also directly displayed, if the export function is retrieved without Wizard. KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 16/41

17 Figure 11: Import Wizard, file selection Product data of previous ETS versions is converted by ETS into XML format. On the next page of the Import Wizard you are asked whether you wish to save the converted files, to avoid having to convert again during later imports. Take care when importing files from CDs. If you have selected the option Save the converted output file, the point of origin of the file is entered automatically as the location where the converted file will be stored. In the case of CDs, this leads to problems as it is not generally possible to write to a CD. You should therefore in this case select a path that is also writeable. If you do not wish to import the complete product database of a manufacturer, you can select which products you wish to import on the next page of the Import Wizard. For this, you must first select Import only selected products. A list of all the existing products in the database is subsequently created and displayed. When selecting the products, a search function and a filter function are available. Mark any products that are to be imported simply by clicking on them. With the help of the Shift key, you can mark a whole range of products. With the Ctrl button, you can select several products. KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 17/41

18 Search function Filter Figure 12: Import Wizard, product selection Finally you can select whether you wish to import all existing languages of the text of the product data (parameter dialogs, etc.) in your database or only those you have selected. If you do not import all languages, the import process is faster and your database remains smaller. Before the start of the import process, a summary shows you again what you have selected Project import The import of projects follows the same pattern as the product data import. During the project import, all project design data such as building structure, comments, group addresses, physical addresses etc. of the corresponding project is imported. In addition, all required product data of the devices contained in this project is imported as well. You can retrieve the project import function on the Dashboard via the Quick Actions bar and under the Projects tab via the Import.button Particularities for plug-in software The following explanatory notes concern both product as well as project data imports for projects containing devices with plug-in software. For many products, additional software is installed when importing the manufacturer data in the ETS database, called plug-in software. You can now decide whether these plugins should always be installed immediately after the import or at a later date or after a KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 18/41

19 single request. They are only required by ETS when the device is retrieved for the first time. If a plug-in had not yet been installed, this can be done at this point. This however frequently requires administrator rights. Many users therefore prefer plug-ins to be installed immediately. Sometimes installation of plug-ins can require a considerable amount of time. In this case, the immediate installation of the plug-in is skipped, particularly if all products of a manufacturer should be imported at once. Whether the plug-in should be installed immediately or not, can be set in the Settings tab under the Import submenu on the dashboard (see section 1.8.5) The export functions You can export product data and entire projects from an ETS database. Product data export Product data export is possible from two windows: from the Catalogs tab on the dashboard and in the project design from the Product Finder window. Depending on the selection in the respective window, individual products, whole product groups, all the products of a manufacturer or all the products of this database are exported. A file with the extension.knxprod is created. The data format of this file is XML and the products can be imported back into an ETS database. It is not possible to create product data for importing into older ETS versions. Project export if in the project administration area and by selecting the Projects tab on the dashboard, one is able to export a project. All the project-related data is exported into a file with extension.knxproj. This file also contains the entire product data of all devices used in this project, so that you can work on the project immediately after importing it into an empty database.

20 2 Opening a project with ETS Figure 13: Creating a new project 2.1 Creating a new project A new project can be created on the dashboard via the New Project function of the Quick Actions bar or under the Projects tab via the button. The New Project dialog appears on the screen. A name must be entered in this dialog window. The medium that has been used is also specified here (TP for Twisted Pair, PL for Powerline and IP for Ethernet). If you have selected the function Create Line 1.1, the area 1, main line 1.0 and line 1.1 are created immediately. Otherwise the project has no topology structure. Finally, one can set the group address style. KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 20/41

21 Double click Click Mark project and press Figure 14: Opening an existing project 2.2 Opening existing projects From the dashboard, there are several options to open a project: Clicking on a project under Recent projects in the Quick Actions bar. Overview tab: Double click on a project in the Projects Overview container. Projects tab: Open the project marked in the list via the button. KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 21/41

22 Figure 15: Project details 2.3 Project details In the Projects tab on the dashboard, you can see the details of the project marked in the list. The details are given in three index cards that can be selected via tabs General index card On this index card, you can change the name of the project and there are further fields for specifying the project. You define here which group address view should be used for this project and you can assign a project password and a BCU password for BCUs supporting this feature. With a project password, a project can be protected against unauthorised access. Each time the project is opened, the password is requested. With the BCU password (BCU=bus coupling unit), BCUs supporting this feature can be protected against unauthorised tampering. The entered BCU password is applies to all BCUs within this project. The BCU password consists of 8 hexadecimal digits (possible values 0 to F). Caution: If you forget the project password, it is no longer possible to access the project as the password in encrypted in the database. KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 22/41

23 2.3.2 Project log index card This index card is used to structure, check and evaluate the project history. With the help of the Add button, the project history can be extended. You need to mark the corresponding line in order to modify an entry or to see the exact description. The entry can then be edited Project files index card Under Project files, you can add other files to the project, which should be saved together with this project in the database. They can be e.g. Word or Excel files or files with drawings. 2.4 Project design views When you open up a project, you access the project design view of ETS. The following screenshot shows the elements of this view. Figure 16: Project design view The numbers in the screenshot designate the following elements: 1: Menu bar 2: Toolbar 3: Panels 4: Navigation bar (side bar) 5: Status bar KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 23/41

24 To a large extend, the project design of a KNX installation is done in the panels. They can be used simultaneously. Panels can be arranged according to the editing process. The following panels are available: Buildings, Group Addresses, Topology, Project Root, Devices, Catalogs and as a special case Side Bar Figure 17: Panels Elements of the panels are: 1: Title bar. By clicking on the title, you can select which panel should be displayed. 2: Toolbar. The tools available depend on the respective panel (context-sensitive) 3. Tree view 4: List view. The list view can have up to three index cards which you can select via the tabs below. Further panels can be opened via the toolbar: View / Open New Panel. Projects can be ordered according to building, function or bus structure hierarchies. One uses the Buildings and the Topology view to structure one s project more clearly. A combination of panels and their exact appearance can be saved as a Workspace. You select the workspaces via the Workspaces container in the side bar. Further information about the creation and storage of workspaces is described in the section on complex project design. KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 24/41

25 Figure 18: Buildings window Buildings window The Buildings view is the central view of ETS. The Buildings view is used to structure the KNX projects according to the actual building structure and to insert the KNX devices. The following elements are available to structure the building: Buildings, Building parts, Floors, Corridors, Stairways, Rooms and Cabinets The buildings, building parts and floors are only used for structuring and cannot directly contain devices. Devices can be inserted in rooms, corridors, stairways or cabinets. A hierarchical view is very useful for maintaining an overview in the case of large projects. KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 25/41

26 Figure 19: Group Addresses window Group Addresses window The Group Addresses window is used to generate and define group addresses. This view is required together with the Building view to link the group addresses to the corresponding communication objects. The group addresses in the Group Addresses window are represented in a two-level, three-level or free style, depending on the preset option. The representation of the group addresses in different levels has no functional effect. It only enhances lucidity. The 3-level structure is used in this documentation. If you select a subgroup, the communication objects that have been assigned to the group address are displayed in the right-hand list view. The tree view (left-hand side) displays the available group addresses (in this case group addresses on three levels). KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 26/41

27 Figure 20: Topology window Topology window The Topology window is used to define the actual bus structure and the assignment of physical addresses to the devices. This view can be used simultaneously with other views and displays the KNX project as regards bus structure. The view shows the devices as they are assigned to the different lines. Twisted Pair, Powerline and IP lines and areas are represented with different symbols. The tree view (left-hand side) shows the existing bus topology of the KNX project while the right-hand side displays a list view of the elements marked in the left-hand window. The structure of the topology is normally generated automatically when physical addresses are assigned elsewhere. All higher-order elements such as areas and main lines are inserted according to the assigned addresses. KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 27/41

28 Figure 21: Devices view Devices window All devices of your project are displayed in the Devices window, including those that have not yet been assigned to a room, function or line. As a result, you can often gain a good overview of your project, for example whether there are devices without an assigned physical address. This list can be very large. It can therefore be very useful to set a filter. Further information on filters is explained in the section on complex project design. With the devices displayed in this window, you can carry out all the tasks that can also be performed in the Buildings window or Topology window: editing devices, editing objects etc Project Root window and Catalogs window The Project Root window combines together the Buildings, Group Addresses, Topology and All Devices windows in one window. One often opens the Catalogs window indirectly when inserting devices in the Buildings window or in the Topology window Side Bar The Side Bar bundles functions and information one frequently requires during project design and commissioning. The side bar is always displayed, except in conjunction with the dashboard. It is located on the right-hand or left-hand side of the screen and can be selected via the menu function Workplace / Side Bar /.... On the dashboard under Settings / View, you can select whether only one container is open in the side bar or several simultaneously. KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 28/41

29 3 Quick project design with ETS Figure 22: Creating a new project 3.1 Starting the project design On the basis of this example, the project design of small KNX projects is explained. The project Goethe School is an example of a quick project design. The New Project window has been opened on the dashboard via the Quick Actions bar. The project name must be entered in the Name: field (in this case: Goethe School). The Group Addresses view is set to three levels (main group / middle group / subgroup). Pressing the OK button after entering the name opens the new project (with two panels Topology and Group Addresses, provided that the Default workspace is set in the side bar). For practical reasons, you should change the Topology panel to the Buildings panel by clicking on Topology in the title bar of the window and then selecting Buildings. You thus have two relatively large Buildings and Group Addresses panels to work in. KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 29/41

30 Figure 23: Creating a building structure 3.2 Creating a building structure In the Buildings window, devices can only be inserted in rooms, corridors, stairways or cabinets. Hence, a minimum building structure must be created first. You must proceed in the following way: 1. Select Buildings in the Buildings window in the left half (tree structure). 2. Click on the symbol in the toolbar. A window opens in which you can enter the name of the new building. If you do not enter a name, the building is designated as New building by ETS. This building should be given an appropriate name, in order to maintain the overview of one s project. 3. You can rename this building at any time. To do so, double click on the corresponding building in the tree structure. The Properties container of the building opens in the side bar, provided it is not already open. You can now enter a new name for the building in the Name field. You can now introduce building parts and floors into the building as system structures. However, to keep this example as simple as possible, we will only insert one room. KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 30/41

31 Figure 24: Adding a room This can be done e.g. via the right mouse button function Add/Rooms. This opens the dialog Add Rooms, where you can immediately give the room a useful name. Further rooms as well as corridors, stairways or cabinets can now be added to the building. You can now also insert devices. 3.3 Product Finder To insert devices, use the Catalogs window. Via the Catalogs window you can insert the device in the currently marked object. It may therefore be useful to select e.g. a room in the device window before opening the Product Finder. You can call up the Catalogs window via the symbol Catalogs window is opened. in the toolbar of the Buildings window. A further KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 31/41

32 Figure 25: Catalogs window Finding products Various functions are available to select the required product/device. On the one hand, you can choose a manufacturer and a product group in the tree structure in the left half of the window: this will limit the number of devices displayed in the list view considerably. It is however also possible to limit the display in the list view with the search function or the filter function (both in the right-hand corner of the toolbar). The selection in the tree structure hereby overrides the search function and the filter function. The narrower the search selection, the fewer products are displayed Inserting devices To insert a product with the corresponding application, select the product in the list view of the Catalogs window with the mouse. Then press the Add button (or double click on the product with the mouse). It is possible to insert in one go a device several times by entering the number of elements that are to be inserted. The physical addresses are automatically assigned by ETS in ascending order in the respective current line. The topic current line is rather complex. If required, consult the help feature of ETS for further information. You can change the physical addresses at any time under the properties of the devices. KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 32/41

33 Figure 26: Properties container of the devices in the side bar 3.4 Properties of the devices The inserted device is displayed in the list view if the associated room has been marked. It will also be shown in the tree structure of the Building view underneath the room. The Properties container in the side bar is opened by double clicking on the inserted device. This container has up to three index cards, which can be selected via tabs. Some index cards only contain information i.e. you cannot make any changes. The Settings card is the most important. It is possible here to change the physical address of the device. A change in the Physical Address field automatically assigns the device to another line and/or another area in the bus topology. Note: Only free addresses can be assigned! It is also possible to add comments about the device in the Description field. A description along the lines what is the device, where is it installed and what is it used for is good practice. Collating information here pays off later during commissioning and fault diagnosis Product information The Properties container of the devices contains further information about a product under the Information tab. KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 33/41

34 Here you can find information about the application of the device. It is also possible to change the application of a device in this container. There is also an index card with catalog information about the respective product. Figure 27: Device parameters 3.5 Device parameters You access the device parameters via the Parameters tab at the bottom of the list view in the Buildings window. To do so, a device must of course be marked in the tree view in the left-hand side of the window. The device parameters can be set here. The parameters define the concrete function of the application program - e.g. in the above example, the sending delay after bus voltage recovery - can be specified. The Parameters window is product-dependent. More detailed information about the individual parameters, application descriptions are available from the manufacturers. The parameters are divided into groups which are listed in the left-hand column of the parameter window. By selecting the individual groups in this list, you access the associated parameters in the right-hand side of the window. The parameters can be reset to the original values as set by the manufacturers via the Default parameters button in the toolbar. The Show Parameter Changes button marks all parameters modified by the user with a red exclamation mark. KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 34/41

35 Figure 28: Editing objects 3.6 Editing communication objects The communication objects of devices (further down referred to as objects ) are displayed in the tree view (left half of the window) below the devices and in the list view (right half of the window) if you have marked a device in the tree view. If you have marked an object in the tree view, you see under the Associations tab in the list view all group addresses that are assigned to this object. You can also make modifications e.g. you can delete the assignment to this object. By double clicking on the individual objects in the list view or by marking an object in the tree view, you open the Properties container of the objects. The properties of the objects can be set here. It is possible to change the default priority of the transmitted telegrams for communication objects, as originally set by the manufacturer. The following priorities are possible: Low High Alarm Low priority for non critical time functions Normal priority for manual functions High priority for critical time functions Note: The priority should only be changed in special cases. The flag of the communication objects can moreover be set here. KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 35/41

36 Figure 29: Representation of the flags Setting the flags The behaviour on the bus can be set for each communication object with the help of the flags (data flow regulation). Below you will find the 4 most important basic settings, depending on the object type: Figure 30: Minimum settings of the flags for actuator objects KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 36/41

38 Figure 33: The update flag For certain masks (System B), it is also possible to set the Read at Init flag: if set, the communication object will automatically send a Read Value telegram after voltage recovery to initialise the value of the communication object. Figure 34: Configuring group addresses 3.7 Configuring group addresses In the case of KNX, devices that should perform a specific function together are logically wired via group addresses. Group addresses can be divided into two or three levels or one can create one s own structuring of group addresses. KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 38/41

39 In the two-level style, the group address consists of a main group (0 to 31) and a subgroup (0 to 2047). In the three-level style, it consists of a main group (0 to 31), a middle group (0 to 7) and a subgroup (0 to 255). The group address is specified by separating the levels by a / (slash) (e.g. 1/0/2). The levels of the group addresses can be set on the dashboard in the Projects tab under Details / General. It is advisable to use the structure of the group addresses as an organisational feature. The group addresses are generated in the Group Addresses window. The group address structure displayed in the screenshot (left window half of the Group Addresses window) is generated via the corresponding buttons of the toolbar in the same way as the building structure of the Buildings window. Figure 35: Assignment of group addresses 3.8 Assignment of group addresses In order to ensure that sensors and actuators know which of their communication objects should communicate with each other to realize a specific function, the group addresses must be assigned to the communication objects. The communication objects are linked logically with each other via the corresponding group addresses ( wired ). KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 39/41

40 In order to assign the group addresses to the objects, it is useful to have two panels open at the same time: the Group Addresses window and e.g. the Buildings window. There are several ways to assign group addresses. The fastest method is via drag and drop: You drag the required group address from the Group Addresses window onto the corresponding object in the Buildings window (or the object onto the corresponding group address) with the mouse keeping the left mouse button held down and then release it. In this way, group addresses are assigned to objects. Figure 36: Sending group address Sending group address A communication object may have multiple connections by assigning several group addresses. If the communication object has the function of a sensor, then the first assigned group address is used as a target address in the telegram (sending group address). If you wish to modify which group address should be the sending group address, this can be done in the Buildings window via the right mouse button, i.e. in the list view (right window half) of the communication objects. Note: There are also sensors, permitting only one address per communication object. The number of group addresses that can be assigned to a communication object and the number of maximum associations (number of assignments per product) are productdependent. It is only possible to create connections with group addresses between communication objects of the same type (1 bit, 4 bit, etc.). The group address receives the type of the communication objects with the first assignment. KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 40/41

41 Figure 37: Group speaker flag Group speaker flag In the case of Powerline devices, the group speaker flag must be set for one object per group address. To do so, you select an object in the Group Address view and click in the list view on the field in the ACK column (PL). A pull-down menu then opens, in which you click on Yes, in order to set the group speaker flag for this object. KNX Project Design ETS4: Basic ETS4_Planning_basic_E1212b 41/41
